回复：I think you misunderstood him/

Thank you for your reply.

Actually there is no annotation on her visa. But on her original visa application form, she applied for 3 months stay.
Since the VO will keep record of the application form (I think so), if she is granted 6 months stay when she enter US, and she did stay 6 months, next time when she apply Visa, the VO might take that as a change of plan and use it to against her. That's what I worried will happen. Do you think I am just worrying too much? I really just want my mom be able to get a visa when she want to next time.
